ADVANTAGE Any factor that increases your winning chances is an advantage. The player who has the most such factors in his or her favor has the advantage in the game; that is, the better winning chances. Specific advantages fall into categories. For instance, if you have fewer weaknesses than your opponent, you probably have an advantage in pawn structure. In Diagram 1, since White's pawns are in fewer groups than Black's, they are easier to guard. Black's pawns have more weaknesses. TIME If you have more pieces developed than your opponent, you probably have an advantage in time. White has a large edge in development in Diagram 2. Note that White has one less pawn than Black. In order to capture the White b-pawn, Black wasted valuable time and moved the queen several times. As a result, Black now has only three developed pieces, while White's seven pieces are all in action. This gives White a winning superiority in time. SPACE Control of the center, more advanced pawns, rooks on open and half-open files -- these are some indicators of an advantage in space. In Diagram 3, White's spatial edge is significant. MATERIAL If you have more men or more valuable men than your opponent, you have an advantage in material. In Diagram 4, White has an extra pawn but Black has a rook compared with White's knight. Black therefore has a slight material advantage. SAFETY If your king is less exposed than your opponent's, you probably have an advantage in king safety. In Diagram 5, White's king is securely castled. Black's is stuck in the center and dangerously exposed. TYPES OF ADVANTAGES Advantages can be temporal, positional, or material. Temporal advantages might include: faster piece development or having been able to force your opponent to make extra pawn moves (instead of developing pieces). Temporal advantages have a way of evaporating, so they should be converted to other types of advantages early in the game. Your opponent will be able to catch up in development (for example) if you don't make something of your early development soon enough. Positional advantages, such as control of the center, good pawn structure, controlling open or half-open files, and obtaining a safe position for the king, change constantly throughout the game. When you play positionally, you are trying for small advantages -- and sometimes your opponent either doesn't realize what you are doing or doesn't consider those advantages important. But although those little advantages may not amount to much individually, when they're accumulated and cultivated, they can eventually add up to a real positional superiority. To neutralize these advantages your opponent may have to surrender material or submit to a strong attack on his king. Material advantages, such as trading a knight for a rook, or a queen for two minor pieces, keeping a good bishop, or trading a bad bishop are usually the most decisive. Advantages in material and pawn structure tend to be more permanent than temporal advantages. If you have an extra pawn, unless something radical happens you will probably still have it ten moves later. Thus, some advantages are more useful, practically speaking, while others are harder to turn into a win. ANALYZING THE COMPETITION POSITIONALLY Try to build your game and increase your overall advantages. Reduce the weaknesses in your own position and increase those in your opponent's. To do this, you must be able to evaluate correctly. You must know how to analyze a chess position.
